What to Consider before you Electroplate

Are you thinking about having parts electroplated?  Here are the most important things you need to take in to consideration before and during the process…

What should you consider Pre Electroplating?

 

  • Nesting

Electroplating involves electrical and chemical reactions on the surface of the part you are wanted to be plated, so exposure is crucial to the result of the final product.  Parts which are nesting will lack adhesion and therefore coverage on the final product.

  • Tolerance

The tolerance on vital dimensions on the part in question should be designated with the plating thickness in mind.  This is should be accounted for when the pieces are ready for assembly after the products have been through the chemical process.

  • Environment and exposure

What is your product going to be exposed to?  A high amount of friction, heat or sea spray?  This is essential for negotiating the thickness of the necessary plating required to maintain the resistance, corrosion and rust protection of the part in question.

  • Geometry

Electroplating involves using a current in order for the reaction to be initiated on the surface of a part, which means that the geometry of the parts surface will influence the distribution of electroplating across the surface.  This is called current density.  It is normal that plating builds up in parts which have sharp corners, bends and threads but it can be prevented if specialists use advanced plating processes.

  • Drainage

The preparation of the surface of a part needing plating must be correct so that the inside surfaces of a part will be sufficiently covered when the process is completed.  This is so that the plating will have the correct bond strength for plating to have been carried out correctly and for the part to have ultimate protection and increase its longevity.  This, for some parts, may mean they need to have a weep hole create during their design phase, so that this can be achieved.

  • Usage

It must be clear what your intended use is for the part you are needing plating.  Make it clear to your specialists what the use and required characteristics are of the part.  Important features include conductivity, low friction, high strength, corrosion resistance, wear, exposure to sea spray or water etc.  This will determine which metal your part is made from (eg. Copper, Nickel, Tin, etc), how your part should be finished and plated.

Electroplating from the Start

Electroplating is a form of metal plating which is used by many industries in a range of capacities which include the aerospace, automotive, army, space, medical, electronic and engineering sectors, to name but a few.  It is useful due to the fact that it is so versatile and lends itself so because of its electrochemical process where metal ions in solution are bonded to metal substrates by means of electrodeposition.

Before Electroplating

Pre Electroplating, all parts must be thoroughly cleaned and then a process of chemical baths must be followed so that the parts can be prepared and activated so that the adhesion for the strong bond can take hold and become effective.  This is key in the electrodeposition process.  Many variables must be monitored closely during the electroplating bath process, such as the power supply which provides a direct flow of current to the parts in submerged.  This enables ions to be attracted to the surface of the metallic part evenly.  Every mole of electrons that are transferred to the part, allows one mole of metallic ions in the solution to adhere to the part during the bath process.  A chemical reaction can subsequently occur where the reduction and oxidation of ions takes place.

Types of Electroplating

Specialist plating facilities are able to plate a large array of different base materials to protect various surfaces.

Base materials for electroplating include:

  • Brass
  • Copper
  • Nickel
  • Stainless Steel
  • Nickel Silver

Surface finishes for electroplating include:

  • Gold
  • Silver
  • Copper
  • Electroless Nickel

About Electroless Nickel Plating

Electroless nickel plating is a high quality but cost effective coating solution which can drastically extend the life expectancy of a stainless steel component.  This is due to the metal layer deposited by the electroless nickel coating creating an even thickness across the components surface, despite its shape.  This makes electroless nickel plating very popular in sectors such as the defence, health, automotive and aerospace industries.

Boeing up in the World

 

 

 

 

 

 

 

The famous aeroplane makers, Boeing, have found what seems to be the “Lightest Metal Ever” known as microlattice.  This is a material which is 99.9% air!  Developed in California, it is a way for planes and even rockets to have their weight reduced.  This 3D open cellular polymer structure will reduce the amount of fuel a plane needs to use during take off, flying and landing.  Currently, Boeing are looking in to using this structure internally on their planes in areas such as the overhead compartments, under the floor and in other fixtures to create a modern internal environment for passengers.

Boeing and Electroless Nickel Plating

Researchers decided that the 3D open cellular polymer structure should be coated with electroless nickel plating, in order to give the structure the required strength, because the web of nickel-phosphorus alloy lattice tubes are only just 100 nanometres thick.  The theory behind using this new structure coated with electroless nickel plating is a lot more advanced in the theory of aeronautical engineering, so has not been trialed yet for space-bound vehicles.  However, it is known that it would be used for exactly the same weight saving reasons to go to space, but also because it has the ability to compress, too, which could mean that objects sent in to space could expand after launch, reducing cargo hold space.  More, evidence will be needed though, before this is trialled as part of a space-bound launch, but nevertheless is a very exciting move forward in science.

Electroless Nickel Plating

Electroless nickel plating as a high quality, cost effective solution for metal coating, elongating the life of a component dramatically, because it leaves an equal thickness metal layer deposit all over the surface of a component, no matter what size or shape it is.  It is ideal for use in harsh environment as it is corrosion resistant, rust is prevented from forming and does not chip or flake which reduces the cost and frequency of repairs and replacement needed.  Electroless nickel plating can be hardened up to 950vhn, is self-lubricating and is non-magnetic.  These are just some of the advantages of electroless nickel plating.  If you would like to find out more then you can find out more by contacting us, the leading suppliers of electroless nickel plating.

15 Reasons To Choose Electroless Nickel for your Metal Plating Needs

When considering a plating method, there are lots of options you can consider. Here at us, we are experts in electroless nickel plating and consider the process superior to many other coatings on the market.

There are many advantages to electroless nickel plating that in our opinion make it a cut above the rest.

For example, electroless nickel:

  • Allows the deposit to coat a variety of surfaces, many of which would be difficult if not impossible to plate using the process of electroplating.
  • Is a very cost effective solution to coating metals such as mild or stainless steel.
  • Can substantially extend the life of a component.
  • Produces a metal layer with a very even thickness over all surfaces of the component, regardless of its shape or dimensions. This means that there is little or no excess deposit at high points on the component.
  • Deposits of electroless nickel have excellent physical and chemical properties, including hardness, wear resistance and lubricity.
  • Creates a uniform coating that makes it ideal for critical high-end engineering items, especially those used in the defense, automotive, healthcare and aerospace industries.
  • Has a high level of corrosion resistance making it perfect for extending the life of anything that it coats. This makes it the perfect solution for parts that are exposed to harsh environments such as the marine, oil, gas and defense industries.
  • Because of its ability to extend the life of components due to its high levels of corrosion resistance, electroless nickel coatings can reduce the cost of repair and replacement parts.
  • Prevents the formation of rust on a component, therefore preventing the parts around it from rusting too.
  • Tight manufacturing tolerances can be achieved with an electroless nickel coating because of its ability to deposit nickel evenly on the surface of a component
  • Can be used to improve the surface of a component so that it is back within the specified tolerances.
  • Provides the surface of the component with a surface layer that allows post finishes to be carried out effectively.
  • Has self lubricating properties which reduce the wear of a component through friction, creating minimal coating weight loss.
  • The use of electroless nickel on a component creates a coating that will not flake or chip off like some paints and lacquers will.
  • Can be hardened up to 950vhn with the appropriate heat treatment.

ABCD – Aluminium, Boron, Coating, Diamonds

Over the last decade, the demand for aluminium moulds has increased dramatically but consistently and apparently this shows no sign of slowing down, changing or ceasing all together.  Metal coatings are provided for a range of fabricated metal components, but the largest business currently is mould coating and plating.  Specifically the demand for aluminium itself is increasing.  This is because companies have begun to discover that that aluminium moulds can last longer, much longer, than what they were predicted.  The extra longevity of the aluminium moulds can be enhanced further if buyers opt for the mould to be plated with electroless nickel.  This is a cost effective way to extend the life of aluminium tooling and has become extremely popular with automotive suppliers.  Alternatives to aluminium coating or plating can be nickel boron plating and nickel diamond plating which are also popular but aluminium remains the optimum and is only set to continue growing in demand.

Nickel Boron Plating

Nickel boron is a surface deposit coating that can be applied to many different metals including stainless steel, aluminium and titanium.  It acts as a great alternative to chrome plating and has many benefits, which include extending wear and corrosion resistance.  The nodular structure of nickel boron reduces drag in aerodynamic and fluids in circumstances such as ship propellers, down-hole oil crude oil pumping equipment, automotive and truck transmissions and greaseless guns.

Nickel Diamond Plating

Nickel Diamond Plating is where electroless nickel deposits are combined with particles of diamonds.  Many substrates can be coated using this method such as carbon, aluminium, stainless steel and alloys.  Substrates, once coated in this, become extremely highly corrosion and wear resistant and therefore have a much increased lifespan.  Part maintenance and replacement costs are reduced dramatically, as are the costs for such.  This is a popular technique in industries such as textile industry, wood working tools, computer parts, paper handling equipment, automotive water pumps, chemical process pumps and gage blocks.

Choose the Right Coating to Maximise Product Optimisation in the Automotive World

The idea of a specialised coating is for the surface of metals to be permanently enhanced by them.  This can be used on other substrates as well and on many components and equipment, too.  These specialised coatings, in effect, act as a deterrent and solve wear, corrosion, lubricant and release problems.   But to choose the best coating for you, the most important things which must be taken in to consideration is the operating environment.

Put a Coat on!

Surface coating usage has grown enormously in the automotive industry over the last fifty years.  Initially, the internal combustion engine was usually manufactured from cast iron, forged steels and die-cast aluminium alloys – Heat treatment provided the wear surface for these elements along with white metal or bronze bearings.  They were oiled and lubricated to allowance clearance between moving surfaces.  Half a century later, this method is still used today, though we need and expect more out of our cars.  We expect them to last longer, drive considerably more substantial distances and we need them to abide by our emissions regulations now, too – no mean feat!  In case that wasn’t enough, we expect our cars to do all of this with less fuel and lighter engines which have a lower tolerance to engineering and lower friction between their moving parts.  Due to this, a wider range of materials and coating variety have been required by us all, so that the wear, corrosion and friction problems and expectations could be overcome.

Automotive Parts and Protective Coatings

Piston rings, skirts and pins are coated frequently by hard-wearing, low friction coatings.  This is to help the initial running-in and advocates long-life performance.  It also helps with lower oil lubrication levels which are commonly associated with cold engine starts and reduces the amount of lubricant allowed to enter the combustion chamber.  Ceramic coatings provide the thermal insulation of piston crowns, usually in diesel engines, where increased and high temperature thermal spray or vacuum use methods are often practiced.

Mating cylinder linings can be coated with electrolytic or electroless plated composite finished which incorporate hard particles of silicon carbide, diamond or boron nitride.  The engines design and performance influence are what enable the design engineer to make the coating choice.

Bio fuels have caused a large amount of corrosive issues with the fuel input systems, fuel storage and fuel delivery systems.  There are a great array of thin coatings which can be applied to these areas in order to prevent corrosion from occurring such as electroless nickel plating which is often enhanced with the use of powder coating or e-coat top coats.

The 3 P’s – Plating, Process and Products

After only a couple of decades, the metal finishing world has been transformed.  Electroplating is the most modern form of metal finishing which is used in a wide array of industries such as aerospace, automotive, healthcare and military defence, to name but a few.  During this electrochemical process the metal ions in solution are bonded to a metal substrate via the process of electrodeposition.

Pre-Electroplating

Before electroplating was a front runner in the metal finishing world, parts had to be properly cleaned before entering a series of chemical baths to prepare and activate in order to prepare and activate the metal to create strong adhesion created during the process of electrodeposition.

The Plating Process

Electroplating baths involve multiple variables and components which must be closely monitored constantly.  The parts have a constant power supply provided directly to them which initiates the ion attraction in the solution towards to metallic surface.  Every time a mole of electrons is transferred to the part in question, one mole of metallic ions in solution adhere directly to the part as well.  Whilst this happens a chemical reaction also occurs on the surface of the part which includes ions being reduced and oxidised.

What do you need to consider before electing to use Electroplating?

  • Because electrical and chemical reactions are both involved in the electroplating process, exposure is critical to the finished product. The nesting of parts will create a lack of adhesion and lack of coverage which should be avoided.
  • Plating thickness should be kept in mind when dimension tolerance is designated and the extra room for electroplating should be left so that parts fit together after the process has occurred.
  • What environment are the parts going to be exposed to? This will help you to decide what level of thickness you will require in order for your part to be made corrosion proof.
  • The geometry of the part in relation to the current distribution aka current density, across the surface of a part. Plating builds up on sharp corners, bends and threads for example.
  • Do you need to think about the drainage of plating solutions the addition of a weep hole may need to be added during its design phase in order for it to be successful.
  • Think about the type of metal you should be using in relating to the job you want it to do for you! What characteristics do you need the surface to have for the job in question?  Does it need to be a conductor, have low friction, be strong, corrosion resistant, hard wearing etc?  This should make you therefore lead you in to thinking about the types of plating which would be effective – Gold plating, Silver plating, Nickel plating or Copper plating

To Be Or Not To Be? That Is The Automotive Question

Before you decide what coating you need to enhance the surface of any metal, you should first think about your operating environment and the impact the coating in question could have, what it could be and what it definitely should not be.

Specialised coatings are used to:

  • Enhance metal surfaces permanently
  • Solve wear
  • Prevent corrosion
  • Increase lubrication
  • Decrease release problems

The Automotive Industry

In this industry, surface coating usage has grown hugely over the last fifty years.  It was then that the internal combustion engine was usually manufactured out of cast iron, forged steel and die-cast aluminium alloys.  Heat treatment was combined with white metal or bronze bearings in order to provide wear surfaces.  These were lubricated by the oil films pumped through large expanses created between moving surfaces. Though they operate in the same way, cars and their engines today must last greater distances, adhere to emissions regulation and aim for  reduced consumption of fuel in order for lighter engines, lower engine tolerance and lower friction between moving parts.  This has meant that a wider array of coatings has become necessary to overcome certain common problems, such as wear, corrosion and friction and aid the long-life performance that our modern cars need.

Automotives Bare All

  • Piston crowns are often coated with thermal insulated ceramic coatings, usually in diesel engines.
  • Mating cylinder linings can be coated with electrolytic or electroless plated composite finishes Silicon carbide, diamond or boron nitride.
  • Fuel storage and delivery systems need electroless nickel plating (especially in bio fuel consuming cars), frequently enhanced by powder coatings or e-coat top coats.
  • Brakes require hard anodising, enhanced by applying paint or powder coating top coats.
  • Brake systems, fluid delivery pipework and air suspension systems use ductile zinc nickel plating.
  • Motors contain neodymium, iron, boron magnets which need TriCem coating and heat treatment, to enhance magnetic performance but to leave the alloys unaffected.

The Importance of…Electroless Nickel Plating and the Benefits

You may be aware of Electroless Nickel (EN) plating, but do you know all about the process of EN and how it could help you in your industry?  This article informs you about the concentration ranges, the environmental legislation by which EN complies and flags up specific industries which it is now prevalent in.  Could Electroless Nickel plating help you?

Process This

The process of Electroless Nickel plating is autocatalytic – A controlled reaction between a nickel-phosphorous alloy and a metal or plastic substrate, without the use of electric current or other external electrical power supply.  The metal being used in submerged in an aqueous solution called a bath, during this chemical reaction.  An agent within the bath, normally sodium hypophosphite, acts as a reducing agent, releases hydrogen, which reacts with the metals ions producing a negative surface charge.  This creates nickel alloy as a deposition on to the metal or plastic substrate.  This method is a reliable, repeatable typical thickness layer which is known to prevent the need for post-plate grinding.  Electroless Nickel plating is often thought highly of due to its mechanical properties, stabilities and brightness which the plating obtains.  This process also provides superior corrosion protection, solderability, lubrication and wear resistance.  Due to these reasons, it has been widely used in the Automotive, Aerospace, printed circuit board industry and Military fields and can be applied to a wide range of base materials such as aluminium, titanium, stainless steel, copper brass and die-cast zinc.  This shows the usage flexibility of Electroless Nickel plating, thanks to its three phosphorus concentration ranges: low (2-5%), mid (6-9%) and high (10-13%).  It is beneficial to these industries because it helps them comply with specific environmental legislations, such as End of Life Vehicle (ELV), Restriction of Hazardous Substances (RoHS), Environmental Protection Agency (EPA), and Occupational Safety and Health Administration (OHSA), to name but a few.

Anything Chrome Can Do, ENP Can Do Better

Electroless Nickel plating is now a good alternative for industries, such as Automotive, Aerospace, printed circuit board and Military, rather than chrome technology – It is more energy efficient, falls inside the engineering requirements and reduces the amount of hazardous waste matter introduced into the environment in comparison to chrome technology.

4 Reasons to Choose Heat Treatment Solutions at us

As experts in metal plating and metal finishing, we also offer high temperature heat treatment solutions. Our heat treatment services expose metal coatings to high temperatures for sustained periods, diffusing the electroless nickel layer onto the steel. These treatments optimise the mechanical and physical properties of a coating for a given application.

Add Flexibility to your Coating

Exposing metal coatings to heat treatment solutions gives them a degree of flexibility. It’s a common misconception that heat treatment is a process for hardening metal, as many heat treatments are applied to soften metal in order to allow metal working operations such as deep drawing, cold forging and machining. The heat treatments at us can be used for stress relieving and de-embrittlement as both pre-plate and post-plate treatments.

Maintain Corrosion Protection

Luckily, the heat treatment process does not affect the increased corrosion protection offered by an electroless nickel deposit.

Small Components can be Treated Economically

Even the smallest of components can be heat treated. We load them onto shelves to maximise the heat treatment capacity and minimise the cost of the treatment for our customers.

Carefully Monitored Heat Treatment

The staff at us use chart recording equipment to monitor the temperature changes of both the furnace and the work. This enables us to create heat treatment profiles which determine shot blasting solutions for many different requirements. Our monitoring also ensures the material achieves the required temperature for the required time, in turn eliminating heat sinks on larger components or mixed loads.

Nickel Plating Services in the Automotive Industry

Electroformed, electroplated and electroless nickel is commonly used in the automotive industry.

One of the biggest and most obvious uses of nickel is the use on bumpers, wheels and grilles. The use of nickel plating on parts such as these is partly due to the fact that it looks good with its shine and bright finish. But nickel also provides excellent corrosion resistance, durability and wear resistance, as is often demanded by makers of vehicles.

Nickel and Industry Warranties

Nickel plating is a great way of metal hardening and can protect components for decades, which is obviously great news for the automotive industry because it means that manufacturers can offer industry warranties.  High quality plated components can be produced in bulk, with consistency and reliability.

The automotive industry is the biggest user of nickel for plating applications. Steel bumpers are very popular as they look great, and they are also very durable. Substrate materials include steel, aluminium and plastic. The benefit of using nickel plating on substrates such as these is that they are relatively cheap, and with a layer of nickel plating they can be made extremely durable.

Environmental Benefits of Nickel

Nickel plating lightweight materials such as aluminium and plastic is also beneficial because lightweight parts on a vehicle improve fuel efficiency. It’s also better for the environment for parts to have a longer life as it reduces scrap. Also, plated components can be recycled, which is good for the European auto industry as their objective is to produce vehicles that are completely recyclable.

If you would like to find out more about metal hardening and metal corrosion protection, or the use of nickel plating in the automotive industry , why not ‘Like’ the us Facebook page or follow @nickelplating on Twitter for regular news, pictures and case studies.

 

Nickel and Computer Hard Disks

It’s truly amazing how far the IT industry has advanced over the past few decades. Laptops, computers and tablets continue to reduce in size, but despite shrinking, they can actually hold more data than ever before.

IBM invented the very first computer disc storage way back in 1956. The disks were about 150cm in diameter, which is roughly twice the size of an old vinyl record, and they could store 100 kilobytes of data. The computer hard disks we use today can be as small as 1cm wide and hold more than 400 gigabytes!

Hard disk drives work by using a magnetic head to move to a location where information is stored. As experts in electroless nickel plating, us have a wealth of knowledge about the use of nickel and the benefits of using nickel in everyday items such as hard drives.

Nickel really is a critical part of the technology involved in hard drives and is used in the film heads. It is applied to the magnetic heads using a plating process that uses heat, not electricity, to deposit the nickel layer.

This film head technology means that the storage density of hard drives has increased by 10 every 8 years since 1979! It also means that hard disk drives can now be used in mobile phones, video games consoles and iPods.

Electroless Nickel – Every Engineer’s Dream!

Here at us, we are extremely proud of our high quality electroless nickel plating services. We routinely nickel plate items for a wide and wonderful variety of applications and industries. This method of plating has so many advantages – which is why we like to call it every engineers dream!

What’s so Great About Electroless Nickel?

Electroless nickel coatings are comprised of a mixture of nickel alloy and phosphorus. This superb combination offers high levels of corrosion protection that are particularly useful in extreme conditions.

Electroless nickel is the perfect metal coating for working to close tolerances, meaning that post-plate grinding is rarely needed. It can be applied to a variety of base materials including stainless steel, iron, steel, brass and copper.

The Advantages of Using Electroless Nickel on Large Parts

Electroless nickel plating large components is a highly efficient method of plating, and can be extremely cost effective too.

us are one of the only electroless nickel plating companies that have the capacity to process large parts. In fact, we have never been approached with a project that we couldn’t fulfil because of its size!

Our staff have even been known to construct bespoke specialist plating tanks to accommodate larger items of unusual dimensions, such as sculptures. Of course, plating large components isn’t all about the size of the plating tank; there are lots of other practical issues to consider as well.

The mass of the part is a factor that needs to be considered. The larger and heavier the part is, the more consideration needs to be taken when moving the part in and out of the plating solutions and around the shop floor. Therefore, care must be taken when thinking about the selection of cranes and fixtures needed to lift the component.

Luckily, here at us, we have plenty of experience handling large parts, and the equipment and man power we need to do so. If you would like to find out more about the process of electroless nickel plating call us , email us at  or visit the contact page on our website to make an enquiry.

Top 3 Benefits of Applying Corrosion Resistant Coatings

Corrosion resistant coatings are incredibly useful in a variety of industries; from aerospace and defence to engineering and automotive. They are able to effectively protect metal parts and components against corrosion, which may include degradation due to moisture, oxidation, salt spray and exposure to a range of industrial or environmental chemicals.

Our metal plating experts at us use a variety of different anti-corrosion coatings depending on the specification and requirements of the customer. This allows for the added protection of metal surfaces and has the advantage of acting as a barrier that will inhibit the contact between the chemical compound of the component and the corrosive material that it is exposed to.

Of course, many of the coatings we offer are not exclusively corrosion resistant; many also offer the qualities of abrasion resistance, chemical protection and non-stick performance.

Resistant to Harsh Chemicals and Extreme Temperatures

Corrosion resistant coatings such as electroless nickel plating and nickel PTFE are resistant to environmental and industrial chemicals, as well as extreme temperatures.

Extended Life Span of Components

One of the major benefits of corrosion resistant coatings is their ability to extend the lifespan of components, ensuring that parts have the longest service time possible.

Servicing Costs Reduced

As parts last longer, the costs of servicing components can be reduced significantly. Downtime as a result of corroded parts is severely reduced or avoided altogether. The use of a corrosion resistant coating means that the costs of repairing, replacing or maintaining parts can be dramatically reduced or avoided altogether.

If you are looking for metal coatings that have outstanding levels of  corrosion resistance, electroless us have the perfect solution. Call us , email us at  or visit the contact page on our website to make an enquiry.

Corrosion and Chemical Resistant Coatings

Here at us, we spend our days electroless nickel plating components for a variety of applications including aerospace, electrical/electronics, the energy industry, and general engineering.

Properties of electroless nickel coatings

Hardness

Electroless nickel coatings produce very tough, abrasion and corrosion resistant surfaces, which can be further hardened with heat treatment. The hardness of the plated surface can also be increased by decreasing the phosphorus content of the coating, usually to around 2%.

Corrosion resistance

They also have a good natural corrosion and chemical resistance. These properties can also be maximised by increasing the phosphorus content of the coating, usually to 10% or above.

Electroless nickel and phosphorous levels

The chemistry of electroless nickel plating solutions can be altered to give the plated coating different properties, for example, a medium phosphorus coating, a low phosphorous coating and a high phosphorus coating.

Medium Phosphorous electroless nickel coating

Electroless nickel coatings with medium phosphorous content are the most commonly used and applied electroless nickel coatings. They generally have a phosphorous content of 6-9% and a VPN of roughly 500. However, this can be increased further with heat treatment. The coating tends to be bright, with a normal plating thickness range of 3-50 microns. Medium phosphorous electroless nickel coatings are very stable and reliable with fast plating rates.

Low phosphorous electroless nickel coating

Low phosphorous electroless nickel coatings contain less than 3% phosphorous and are very hard. With the appropriate heat treatment, a low phosphorus coating can be in the region of 1000 Vpn. The normal plating thickness of this type of coating is in the region of 10-25 microns and is grey/silver in colour.

High phosphorous electroless nickel coating

Electroless nickel coatings with high phosphorous contents typically have very high levels of corrosion and chemical resistance. High phosphorous coatings are non-magnetic, silver/grey in colour and have a normal thickness range of 25-75 microns. Plating rates are typically slow and the plating solution tends to have a short life.
